IPC: B29C65/48
Filed: 1994-07-27
Abstract: Seat cushions and backs comprising a foam bun and a trim cover are made by applying a hot melt bead to the trim cover or the foam bun in a predetermined pattern that matches or produces style conformations in the seating portion, pressing the trim cover and the foam cushion together in localized areas within a predetermined amount of time with a tool that has railsarranged in the same predetermined pattern to establish intimate contact of the cover and bun with the hot melt bead, and holding the trim cover and the foam cushion in intimate contact with the hot melt bead for a predetermined amount of time while the hot melt bead cools and bonds the trim cover to the foam cushion beneath the style conformations. The tool or at least the rails preferably provide a heat sink to facilitate cooling the hot melt adhesive bead.The bonding method can be used with a wide variety of seating materials including heat-sensitive seating fabrics and laminates and foam-backed seating materials.

Title: Bathtub body support
Inventor: LEGER GEORGE
IPC: A47K3/12
Filed: 1994-11-17
Abstract: Four and a half to five foot modern bathtubs of the kind found in most homes in North America are designed to hold an adequate volume or water for bathing while in a sitting position. Bathing while immersed in water in a supineposition has been found to be uncomfortable for most people due to the inadequate spinal support of the bathtub. Because of this lack of spinal support of the interior design configuration of the four and a half to five foot modern bathtub, a need for body support devices has been desired. Existing bath support devices of the type used with modern four and a half to five foot bathtubs have been inflatable neck and head supports or extendable boards or trays enabling support of the head and neck for shampooing or washing.
